Shear Induced Orientation In Polymer-Clay Solutions And Their Influence On The Structure In Multilayered Films, Matthew Michael Malwitz

LSU Doctoral Dissertations

The influence of shear on viscoelastic solutions of poly(ethylene oxide) (PEO) and clay (Cloisite, CNA) was investigated by rheology and small angle neutron scattering (SANS) under shear. These measurements determined the shear-induced orientation of the clay and the polymer as well as their relaxation behavior after cessation of shear. Comparison of PEO-CNA solutions (~100 nm diameter platelets) to previously studied PEO-Laponite gels (~30 nm diameter platelets) found that the orientation of CNA platelets occurs at much lower shear rates. Additionally, the relaxation times were much longer for CNA platelets than for Laponite platelets. From these solutions and gels, multilayered nanocomposite …

LSU Doctoral Dissertations

This research study was designed to investigate correlations between invented spelling patterns and beginning reading for low-performing and on-level boys and girls in kindergarten. Two research questions were examined: (1) Is there a statistically significant relationship between invented spelling as displayed in task and reading skills as measured by DIBELS? and (2) Does the performance displayed in task and reading skills as measured by DIBELS differ significantly for boys and girls in kindergarten? Student performance data was gathered using extant school Dynamic Indicators of Basic Early Literacy Skills (DIBELS) benchmarks at collected at midyear of kindergarten. It was hypothesized that …

Ecotoxicology Of Metal-Hydrocarbon Mixtures In Benthic Invertebrates, Kurt A. Gust

LSU Doctoral Dissertations

Metal-hydrocarbon mixtures are becoming increasingly prevalent in natural environments due to expanding industrial activity and urbanization. The ecotoxicology of metal-hydrocarbon mixtures in benthic environments is of particular concern because both classes of contaminants partition to sediments and can thereby exert toxic effects in benthic organisms. Mixtures of dissimilar chemicals (including metals and hydrocarbons) are broadly hypothesized to elicit independent toxic effects however; this hypothesis has little supporting data. The purpose of this dissertation was to test this hypothesis for metal-hydrocarbon mixtures using environmentally relevant exposures and to determine mechanisms for observed interactive effects. Sediment and water-only bioassays were conducted employing …

Effects Of Spaced Retrieval On Memory And Quality Of Life In Older Adults With Probable Alzheimer's Disease, Karri S. Hawley

LSU Doctoral Dissertations

This study was designed to explore the effects of spaced-retrieval training on memory and quality of life in older adults with probable Alzheimer’s disease. A total nineteen older adults with probable Alzheimer’s disease (AD) participated in these experiments. Experiment one was designed to determine whether the spacing effect is contributing to the success of the spaced-retrieval intervention. Participants were trained to recall a name-face association using either the adjusted spaced-retrieval method or a fixed interval retrieval method. The results showed a more consistent performance profile for the spaced retrieval group in comparison to the fixed interval group, providing evidence that …

Winter Bird Use Of The Chinese Tallow Tree In Louisiana, Michael John Baldwin

LSU Master's Theses

Chinese tallow (Triadica sebifera) is a non-native invasive tree that is of particular concern in the Southeastern United States. It has become naturalized in a variety of habitats and can be found in monospecific stands. The use of tallow woodlands by overwintering birds is poorly documented. I compared use of tallow woodlands to use of bottomland hardwood forests by birds in the Mermentau River Basin, Louisiana. Species richness and evenness were greater in the bottomland hardwood sites. Three species were more abundant in tallow woodlands, six species were more common in bottomland hardwoods, and six species exhibited no difference between …

A Robust Noise Spectral Estimation Algorithm For Speech Enhancement In Voice Devices, Brett Joseph Chessher

LSU Master's Theses

In this thesis, a new robust noise spectral estimation algorithm is proposed for the purpose of single-microphone speech enhancement. This algorithm can generate the optimal noise spectral estimates in the Minimum Mean Square Error (MMSE) sense based on the speech statistics in the noisy environments. Compared to the well-adopted conventional noise spectral estimation method using the single-pole recursion, our proposed scheme is more reliable since the recursion coefficients are adaptable and optimal in the MMSE therein. We also propose a new accurate Resulting Signal-to-Noise Ratio (R-SNR) estimator as a quality measure to benchmark the existing noise spectral estimation techniques. This …

A Radiographic Study Of The Impact Of Race And Sex On 1st And 2nd Molar Development, Suzanne Price

LSU Master's Theses

The assessment of child development requires standards in order to compare an apparent physiologic age to an actual chronological age. In assessing chronological age of an individual, the use of multiple indicators is ideal and important in determining age at death. For individuals under the age of about 21 years, dental development is the most reliable indicator of age. Research aimed at understanding the variation in tooth formation due to race and sex will help to more accurately determine the age at death of remains of subadult individuals. This project examined the impact of race, sex, and time period on …

Development Of An Alternative Approach To Estimate Vehicle Miles Traveled Using A Classification Procedure, Srividya Vadlamani

LSU Master's Theses

In this study a Classification and Regression Tree (CART) classification system method was developed as an alternative to the HPMS conventional method of VMT estimation. Louisiana Highway Performance Monitoring System (HPMS) data from Federal Highway Administration (FHWA) and Louisiana highway network data from Louisiana Department of Transportation (LADOTD) were used to carry out the analysis. The CART classification was derived based on link attributes that effectively distinguished the homogeneous traffic volume sections. VMT estimation on individual links as well for the different systems was calculated using the CART classification system and the values were assigned on each link. The default …

Defining Modernity: Mentality And Ideology Under The French Second Empire, Gavin Murray-Miller

LSU Master's Theses

This study intends to examine the relationship between popular conceptions of modernity and Republican ideology during the Second Empire, 1852-1870. With the advent of the industrial revolution in France, scientific knowledge came to be equated with notions of progress and innovation, leading intellectual elites to design philosophical and social systems predicated upon the authority of scientific analysis and objectivity. Influenced by the intellectual currents under the Second Empire, a new generation of Republican political theorists incorporated notions of science into their ideological outlook, ultimately engendering a moderate brand of Republicanism which played a significant role in the founding of the …

Dragos Tanasescu's Treaties Of Pianistic Technique, Lucian B. Zidaru

LSU Doctoral Dissertations

This study examines Dragos Tanasescu's fingering system and technical exercises presented in Treatise of Pianistic Technique. The Treatise contains four books, each one dedicated to a segment of technical problems. Tanasescu's main contribution to the piano technique is the applications of math permutation formulas to create all possible arrangements of fingering patterns. His treatise continues previous technical approaches of A. Kullak, F. Liszt, J. Pischna and E. Dohnanyi. Earlier methods organize the technical material by one principle: fingerings. The purpose of this study is to illustrate the characteristics of Tanasescu's fingering system presented in Treatise of Pianistic Technique, and provide …

"I Cried Out And None But Jesus Heard!" Prophetic Pedagogy: The Spirituality And Religious Lives Of Three Nineteenth Century African-American Women, Elecia Brown Lathon

LSU Doctoral Dissertations

African American women represent a long line of prophetic women. Women who fought for space in the religious world of the nineteenth century, and who fought to have their voices heard in America. The lives and experiences of such women have been excluded, ignored, and dismissed from academic discourses. This study adds a new dimension (the spirituality of African-American women) to the field of curriculum theory and builds on the scholarship of literary scholars who have and are currently recovering the lost lives of African American women and their spirituality. Therefore, this research examined the spirituality and rhetorical strategies utilized …

Java As A Western Construct: An Examination Of Sir Thomas Stamford Raffles' "The History Of Java", Natalie A. Mault

LSU Master's Theses

Among nineteenth-century books on Indonesia published in England, Sir Thomas Stamford Raffles’ "The History of Java" holds a unique position. While serving as Lieutenant Governor in Indonesia, Raffles went to great length in documenting the island’s history, culture, architecture and contemporary civilization. His observations were published in a two-volume study entitled "The History of Java," whose most outstanding feature is the sixty-six engravings it includes. Ten of these engravings are colored aquatints by William Daniell, illustrating Javanese life and costume. Published in 1817, Raffles’ "History of Java" is considered, to the present day, a highly important work, particularly because of …

Population Dynamics Of Clausocalanus Furcatus (Copepoda, Calanoida) In The Northern Gulf Of Mexico, Hongsheng Bi

LSU Doctoral Dissertations

Copepods are important components of marine ecosystems. Understanding copepod population dynamics can help interpret variations in both primary producers and higher trophic levels. Egg production, stage duration, and stage-specific mortality rates are key parameters describing copepod population dynamics. Estimation of stage-specific mortality is complicated due to a complex life history, patchiness, and sampling biases. This study was undertaken to quantify the population dynamics of the copepod Clausocalanus furcatus in the northern Gulf of Mexico and to assess the utility of available mortality estimation methods in a highly advective environment. Zooplankton samples were taken every 12h from March 18-April 6, and …

Serotonin And Stress Responding In Animals: Role Of 5-Ht.2a/C Receptors In The Central And Peripheral Nervous Systems, Sarah Mathews Uzelac

LSU Doctoral Dissertations

Behavioral responses to stressors can be influenced in different ways by both serotonin (5-HT) agonists and antagonists. Further study, of both different stressors as well as different 5-HT agents, is needed to clarify the place of 5-HT in stress responding. To date, no published report has investigated the influence of centrally and/or peripherally administered 5-HT2A/C agonist DOI or the 5-HT2A/C antagonist ketanserin on behaviors evoked by tail pinch or open field stressors. Five separate, related experiments were conducted to investigate this influence. It was hypothesized that that peripherally (Experiment 1), centrally (Experiment 2), and centrally + peripherally (Experiment 3) injected …

Lawyers, Democracy, And Dispute Resolution: The Declining Influence Of Lawyer-Statesmen Politicians And Lawyerly Values, Jeffrey W. Stempel

Scholarly Works

This Comment reviews the shrinking presence of lawyers in the arena of macrocosmic public policy. It also discusses the declining statesmanship of lawyer-politicians as part of a general decline of lawyer professionalism in the face of social and economic pressures tending to undermine lawyer professionalism. Furthermore, it addresses how the net impact of these factors undermines the potential of lawyers to act as a positive force for public policy dispute resolution.

Comparative Studies Of Sperm Cryopreservation Of Diploid And Tetraploid Pacific Oysters, Qiaoxiang Dong

LSU Doctoral Dissertations

This dissertation addressed comparative studies of sperm cryopreservation of diploid and tetraploid Pacific oysters, Crassostrea gigas, with an emphasis on the development of standardized and optimized protocols. This includes comparative ultrastructural differences between sperm from diploid and tetraploid oysters, methods for the rapid estimation of sperm concentration, optimization of cryopreservation, and evaluation of the mechanisms for sperm agglutination (formation of clumps or elongated "noodles") in thawed samples. Currently, cryopreserved sperm has not been commercialized in any aquatic species, and standardization and optimization could greatly benefit the potential commercialization of its use. In oysters specifically, cryopreserved sperm from tetraploids would facilitate …

The Operational Aesthetic In The Performance Of Professional Wrestling, William P. Lipscomb Iii

LSU Doctoral Dissertations

This study analyzes the relationship between professional wrestling as performance and its fans. For decades, professional wrestling has been characterized as a fraudulent sport of scams and illusion rather than actual and fair competition between athletes. Why then is wrestling so popular? I pursue the question by taking a close look at professional wrestling in four different cultural venues or sites of production: the historical archive, the live wrestling event, the televised event, and the Internet. In each site, I focus on what components define professional wrestling, how they operate, and what appears to be their purpose. Drawing on Neil …

The goal of this thesis was to evaluate temperature effects on cell proliferation of eastern oyster somatic tissues for the development of an oyster cell line. Understanding the in vivo cell proliferation of an organism is essential for the development of cell culture. Cell proliferation can be measured by identifying nuclear cellular proteins involved in growth regulation and cellular transformation. The primary objectives of this study were to: 1) develop an assay to evaluate cell proliferation, 2) develop an assay to analyze nuclear RNA content, and 3) evaluate temperature effects on cell proliferation in somatic tissues. Proliferating cell nuclear antigen …

Weight Concern And Smoking In Children, Darla E. Kendzor

LSU Master's Theses

Studies have shown that weight concern is prevalent in children and that many children believe smoking can be used to control appetite and weight. However, little is known about the impact of the combination of these factors on smoking initiation in children. Initial research has indicated that weight concern predicts smoking initiation in adolescents, but these studies have not addressed the role of weight control outcome expectancies. The purpose of this study was to prospectively investigate the relationship between weight concern and smoking initiation, and to evaluate weight control outcome expectancies as a moderator of this relationship in children. Cross-sectional …

Palm Is Expressed In Both Developing And Adult Mouse Lens And Retina., Meryl Castellini, Louise V Wolf, Bharesh K Chauhan, Deni S Galileo, Manfred W Kilimann, Ales Cvekl, Melinda K Duncan

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Paralemmin (Palm) is a prenyl-palmitoyl anchored membrane protein that can drive membrane and process formation in neurons. Earlier studies have shown brain preferred Palm expression, although this protein is a major water insoluble protein in chicken lens fiber cells and the Palm gene may be regulated by Pax6. METHODS: The expression profile of Palm protein in the embryonic, newborn and adult mouse eye as well as dissociated retinal neurons was determined by confocal immunofluorescence. The relative mRNA levels of Palm, Palmdelphin (PalmD) and paralemmin2 (Palm2) in the lens and retina were determined by real time rt-PCR. RESULTS: In the …

Fairness And Farmland Preservation: A Response To Professor Richardson, Mark W. Cordes

Faculty Articles, Papers, and Other Scholarship

In a recent article published in this Journal, Professor Jesse Richardson attempted to refute the arguments proposed by myself and others that support the fairness of downzoning land without compensation to property owners. Central to most farmland preservation efforts is agricultural zoning, which typically involves downzoning farmland to agricultural use, precluding more intensive development. Part IV will briefly comment on the role compensatory programs like PDRs and TDRs should play in effective farmland preservation programs. This is true even if downzoning results in substantial diminution of land values, which means that local governments can pursue farmland preservation by putting the …

Anglian Leadership In Northumbria, 547 A.D. Through 1075 A.D., Jean Anne Hayes

LSU Doctoral Dissertations

The Anglo-Saxon kingdoms of Britain were founded in warfare beginning in the fifth century. These kingdoms developed alongside the native Romanized Britons, who attempted to reassert their authority in Britain in the wake of the Roman withdrawal. Northumbria, located north of the Humber River, the largest and most northerly of the Anglo-Saxon kingdoms played a vital role in the politics of early medieval Britain. During the seventh century, the Northumbrian kings were recognized as the overkings of the Anglo-Saxon kingdoms, as well as the neighboring British and Pictish kingdoms. Over the course of several centuries, the leaders of Northumbria alternately …

Comparative Analysis Of Conventional And Ici-Self-Cancellation Digital Video Broadcasting Transceivers, Khaled Z. Matarneh

LSU Master's Theses

Digital video broadcasting–terrestrial (DVB-T) is one of the important technologies in the communication area because of its capability of high data-rate multimedia transmission. Orthogonal frequency division multiplexing (OFDM) has been the backbone technique in the current DVB-T systems adopted by Europe and Japan. However, since the OFDM system is very sensitive to the frequency synchronization and phase errors, which will induce the intercarrier interference (ICI), the ongoing research has been dedicated to this ICI problem in the presence of the Doppler frequency drift and the fading channels. A means to deal with the ICI problem is called the ICI self-cancellation …

Export-Led Growth In Honduras And The Central American Region, Hermann Castro Zuniga

LSU Master's Theses

This thesis examines the validity of the export-led growth (ELG) hypothesis in Honduras and compares the Honduran experience to that of other Central American countries, specifically Costa Rica, El Salvador, Guatemala and Nicaragua. It further evaluates the ELG hypothesis for the agricultural sector of Honduras. The conceptual model incorporates exports into a Cobb-Douglas production function and formulates dynamic econometric models of real gross domestic product (GDP), real gross fixed capital formation (GFCF), labor and real exports for the 1970-2000 period. To test for the validity of the ELG hypothesis, Granger-causality was tested on the export coefficients of the growth equation …
